Sgt. Jason Mitchell McClary died Sunday at the military hospital in Landstuhl, Germany. He was 24 years old and from Export, Pennsylvania.
Three other service members were killed in the explosion last Tuesday near Ghazni, and two others were wounded.
It was the deadliest attack against U.S. forces in Afghanistan this year. The Taliban claimed responsibility.
McClary was assigned to 1st Stryker Brigade Combat Team, 4th Infantry Division, based at Fort Carson, Colorado.
